Title: Wheel drive mechanism
IPC: B60K17/04
Filed: 1963-09-24
Abstract: 996,448. Change-speed gear. CATERPILLAR TRACTOR CO. Sept. 24, 1963 [Nov. 5, 1962], No. 37505/63. Heading F2D. [Also in Division B7] In an hydraulic motor wheel (see Division B7), change-speed gearing mounted in the wheel hub comprises first and second epicyclic gear trains 18, 19, 20 and 24, 25, 26 controlled by a fluid actuated brake assembly 16 to drive the wheel through an epicyclic reduction train 22, 28, 50 at either of two forward speeds. In the first epicyclic train the sun gear 18 is splined to the output shaft 14 of an hydraulic motor (not shown), the carrier 21 of the planet gears 19 is splined to the sun gear 22 of the reduction train, and the ring gear 20 engages a brake disc 36. In the second epicyclic train, the sun gear 24 is connected to the ring gear 20 of the first train by an annular member 23, the carrier 40 of the planet gears 25 engages brake discs 42, and the ring gear 26 is connected to an annular member 27 splined to the sun gear 22 of the reduction train. The ring gear 50 of the reduction train engages the fixed housing 37 of the brake assembly 16, and the carrier 46 of the planet gears 28 is secured to the wheel 10. When low ratio is selected by supplying fluid through a conduit 17 to an annular piston 45 to brake the planet carrier 40, torque input from the sun gear 18 to the planet gears 19 is transmitted to the sun gear 22 partly by the planet carrier 21 and partly through the ring gear 20, the annular member 23, the sun gear 24, the planet gears 25, the ring gear 26 and the annular member 27. When high ratio is selected by pressurizing an annular piston 38 through a conduit 29 to brake the ring gear 20, torque input to the sun gear is transmitted through the planet gears 19 and their carrier 21 to the sun gear 22 whilst the planet pinions 25 and their carrier 40 rotate idly. When neither conduit 17 or 29 is pressurized, the drive is disconnected.

Abstract: 1526805 Mechanical interrupters DUCELLIER & CIE 12 Sept 1975 [24 Sept 1974 9 Jan 1975] 37547/75 Heading H1N An ignition distributor has a contact-breaker in which an adjustable support 12 for the fixed contact 11 is provided with a housing 103 in which a nut 102 threadedly engaged with an adjustment screw 100 pivots to permit angular divergence between the axis of said screw 100 and said support 12 when the support 12 is moved by rotation of the screw 100. As shown, a spring 109 takes up backlash, and the head 101 of screw 100 is accessible outside the distributor housing 6 for adjustment of contact spacing without removing the distributor cover. The plate 12 is secured to a movable plate (19, Fig. 1, not shown) arranged to be adjustable about the pivot axis of the contactbreaker arm (1). In a second embodiment (Fig. 3, not shown) the plate 12 is movably located on a fixed base-plate (5) by means of two arcuate slots (200, 206) centred on the contact-breaker arm pivot axis such that plate 12 again moves concentrically with arm 1. In this embodiment the adjusting screw axis is arranged so that, over the possible range of adjustment, the nut is always misaligned on the support thereby ensuring consistent taking up of play in operation and during adjustment.

Abstract: 1300160 Ultrasonic testing COMMISSARIAT A L'ENERGIE ATOMIQUE 4 Aug 1970 [18 Aug 1969] 37574/70 Heading H4D A device for measuring the position of a discontinuity in a fluid comprises two probes each including a piezo-electric transducer, a waveguide, a mirror reflecting sound waves from the waveguide on to a surface, said surface being for one probe a fixed reflector whose position is known and for the other probe the discontinuity; and a signal generator and receiver connected to the probes through a transmitreceive switch. The position of discontinuity 9, which may be an object or the fluid level, inside a nuclear reactor is determined by measuring the transit time, t, of n pulses from the waveguide 2 to the reflector. The other probe is used to measure the sound velocity, v, in the fluid. The displacement I is given by vt/2n. The transit times are measured by apparatus identical with that disclosed in Specification 1,300,159, a further changeoever switch being provided to connect the two probes alternately to the receiver. Tubes 10 are provided to prevent turbulence in the liquid sodium 5 across the measurement paths.

Title: Method of adjusting the operating range of a transistor amplifier
IPC: H03F1/30
Filed: 1977-09-08
Abstract: In this method, a transistor amplifier sets its operating point into a distortion-free operating range when it is switched on, and when the operating voltage changes, within an oscillation period of the signal to be amplified. For this purpose, a monitoring circuit (18) with two threshold circuits is provided at the output (7) of the transistor amplifier (1), to switch on a negative feedback to correct the operating point each time it goes above or below the operating range. The amplifier is particularly useful in telephone system subscriber's apparatus which is powered via subscriber connection lines. <IMAGE>
